［摘要］結(jié)合實(shí)際工程項(xiàng)目，研究了多塔高位連接體與塔樓之間采用剛性連接、半剛性連接和滑動(dòng)連接的結(jié)構(gòu)方案。對不同剛度連體的實(shí)現(xiàn)方式、連接構(gòu)造進(jìn)行了介紹，并研究了在連接體中設(shè)置屈曲約束支撐阻尼器，形成半剛性連體的可行性。從連接體剛度、連接構(gòu)件內(nèi)力、結(jié)構(gòu)整體抗震性能、連接實(shí)現(xiàn)難易程度、結(jié)構(gòu)經(jīng)濟(jì)指標(biāo)等方面，對不同連接方案進(jìn)行了評估，指出在塔樓自身具有較好結(jié)構(gòu)條件的情況下，采用阻尼耗能裝置或者優(yōu)化連接體構(gòu)件截面形式，從而合理弱化連接體剛度，減少連接體對塔樓的附加影響是較為合理的解決方案。

Abstract:Base on actual engineering projects, the structural schemes of rigid connection, semi-rigid connection and sliding connection between multi-tower high-position conjoined structure and multi-towers were studied. The realization way and connection structures of different rigid connections were introduced. The feasibility of forming semi-rigid connection by setting buckling-restrained braces was studied. Different connection schemes were evaluated based on rigid of connection, internal forces of connection members, integral seismic performance of the structure, construction difficulty of connection, structural cost etc. It was pointed out that when the tower itself had good structural conditions, it was a reasonable solution to adopt damping energy-dissipated device or optimize the cross-section form of connection members, so as to rationally weaken the rigidity of the connection members and reduce the additional impact of the connection on the tower.
Keywords:conjoined structure; high-rise building; seismic performance; energy dissipation; flexible connection
